A narrow fabric or tubular fabric made from various yarns. There are a wide variety of belt fabrics, which are widely used in various industrial departments such as clothing, footwear, luggage, industry, agriculture, military supplies, transportation, and so on. In the 1930s, weaving belts were all produced in manual workshops, using cotton and hemp threads as raw materials. After the new establishment, the raw materials for webbing gradually developed into nylon, vinylon, polyester, polypropylene, spandex, and viscose, forming three major types of process technologies: woven, knotted, and knitted. The fabric structure includes plain, twill, satin, jacquard, double layer, multi-layer, tubular, and combined weave.

1、 Woven (woven) warp and weft interwoven. After twisting, the yarn is warped into a bobbin (pan head), and the weft yarn is spun into a filament, which is woven onto the ribbon. In the 1930s, it was used for weaving belts on hand drawn wooden looms and iron wood looms. In the early 1960s, the 1511 loom was converted into a belt loom, which is still widely used. Due to the small width of the belt, the weaving methods are different, ranging from single, double, and dozens of strips, ranging from single to double layers.

In 1967, the industry's shuttleless belt research group, which is mainly composed of workers, successfully designed and manufactured a high-speed single shuttleless belt loom, realizing that the belt does not need shuttles, the process is shortened, the floor area is small, and labor productivity is improved. This is a pioneering work in the weaving process.

In the 1970s, due to the promotion of continuous belt dyeing and ironing machines, the processing of colored belts evolved from a traditional process of dyeing before weaving to a continuous process of weaving before dyeing, weaving before bleaching, and ironing after processing. Ribbon technology entered the ranks of mechanized mass production. In the early 1980s, the industry introduced high-speed shuttleless weaving machines from Switzerland, Italy, and the Federal Republic of Germany, as well as ironing machines, wrapping machines, and warping machines. The weaving technology entered a new stage of development.

The advancement of weaving technology has brought about the upgrading of products. In 1979, the successful trial production of domestic generation SD9-9 rubber ingot belts ended the history of rubber ingot belt products relying on imports. In 1980, SD-81A and B type rubber ingot belts were developed, which are characterized by softness, lightness, thinness, firmness, small elongation, small impact force, and short and flat joints. At the beginning of 1990, the trial production of car safety belts for Santana cars was successful. After more than two years of research and organization of trial production, the product quality has reached the QC49-92 and TL-VW470 standards.

2、 After knitting (spindle weaving) yarn is wound and rolled into a weft tube, it is inserted into the fixed tooth base of the knitting machine. The weft tube rotates and moves along an 8-shaped track to draw the yarn to cross weave with each other. Usually, the number of spindles is even, the woven belt is tubular, the number of spindles is odd, and the woven belt is flat. Spindle weaving technology has been used since the old days, and the number of spindles varies from 9 to 100 depending on the equipment. The basic weaving process is: bleaching and dyeing - weft winding - weaving - dropping machine shearing - packaging. Since 1960, many technological innovations have been carried out on the knitting machine, mainly including enlarging the diameter of the peach board, installing an automatic stop device for breaking rubber bands, and replacing the iron ingot with a nylon ingot. These equipment improvements have increased the vehicle speed to 160 to 190 rpm, doubled the stand rate, and greatly improved product quality.

Knitting can not only weave tapes, but also weave ropes. Tubular tape is a type of braided rope, with a diameter of 1 to 4 centimeters called rope or cord, a diameter greater than 4 centimeters also called rope, and a diameter greater than 40 centimeters generally called cable or cable. In 1989, the industry introduced Japanese 8-strand cable production line equipment and produced polypropylene 8-strand cable the following year, winning a silver medal for the product.

3、 In the 1970s, warp and weft knitting techniques were widely used in webbing. In 1973, the trial production of knitted nylon wide band was successful. In 1982, we began to introduce Italian crochet machines with a wide range of processes and production varieties, especially suitable for thin decorative belt fabrics, such as lace, elastic bands, window screens, decorative bands, and so on. The basic process flow is: bleaching and dyeing - winding - weaving - ironing - packaging.

Before the 1970s, fire hose tube blanks were woven on a flat loom, resulting in large diameter deformation and low output. In the second half of 1974, the industry organized a research and development team for tube weaving. Based on the principles of knitting, warp and weft shuttle weaving was adopted. During the looping process, the non woven warp and weft yarns were connected into a whole by using the cylinder and settling arc of the looping yarn, resulting in a tubular knitted fabric lined with warp and weft. The production technology level of the product's plastic coated outlet pipe and high-pressure fire hose ranked first.
